' HINGE.

Application filed June 23, 1924. SerialfNo. 721,626.

This invention relates to improvements in hinges generally, although more particularly to hlnges adapted for use in connection,

with refrigerator doors.

Heretofore, it has been the practiseto construct these hinges from sheet metal and to form one of the leaves with an upwardly extending flange which is formed into bearing eyes for the pintle. The metal at the juncture or bend between the flange and the body portion of the hinge leaf is neces sarily weak and is subject to severe strains which result in the flange being ruptured from the body portion.

The principal object of my invention is,

therefore, to provide a hinge leaf formed of sheet metal and constructed in a manner to sufficiently reinforce the juncture between the flange and the body "portion whereby a rupture of-that juncture will be prevented. y Y

Another'object of the invention is to provide a novel method of producing such a hinge section from sheet metal;

In the accompanying drawingswhich show .myimproved hinge and the method of forming same,

Figure 7'is a plan view of the blank from which the other leaf of the hinge is formed, Figure 8 is a plan view showing the mar ginal side portions of said blank folded to form a depending re-inforcing flange,

-Figure 9 is a longitudinal sectional view taken on the line 9-9 of Figure 8, and,

Figure 10 is a side elevation of a hinge constructedin accordance with my invention. My invention is directed to a hinge which is adapted especially for use in connection with refrigerator doors and this hinge includes pivotally connected leaves A and B 'which are formed from sheet metal.

In. forming the leaf A I stamp or other- -wise cut a blank 5.fro1n sheet metal stock so as to form a body portion 6 and a plurality of outer tongues 77 and an intermedi ateton'gue 8, all of said tongues projecting 1n the same general dlrectionfrom one end of the body portion. The intermediate tongue 8 is spaced equidistant from the outer tongues 77 and extends beyond the ends of said tongues for an appreciable distance. Thebody portion 6 is punched to form openings 9 for receiving attaching screws and the tongues 7-7 are respectively punched to provide bearing openings 1010. After the blank has thus been formed, the intermediate tongue 8 is then rolled to form an intermediate bearing 11, as shown in Figure 2. f i

The blank is then shaped to the contour shown in Figure 3, thereby forming the tongues "7-7 into bearing arms 1212 which extend from the marginal side portions ofthe body portion and have their lon-' gitudinalaxes disposed at approximately 90 to each other. I 7

The article as thus formed is then subjected to a pressing operation which results I in bending 'themarginal side portions down war'dly, together with the bearing arms 12,

shown in Figures 4 and 5 on the drawing, this operation forming resultantre-inforcing' fianges13 for the body portion, and causing the bearing arms 12 to be projectedabove the plane of the body portion.

Simultaneouslywith this pressing operation the screw holes 9 are depressed to receive the heads of the attaching screws.

It is desired to project the bearings above i the plane of the body portion, and also to straighten the lower edge of thebent over marginal portions whereby the leaf will set firmly against its support. The leaf is therefore subjected to a swaging operation Whichraises the hinge end of the leaf and simultaneously straightens the lower edge of the bent over marginal portions as shown in iii) Figure (i. This sw nging operation positions the bearing (winnings lO -lll above the plane of the body portion. The intermediate bearing 11 is, of course, raised into alignment with the bearing winnings l.O--'l.0, and this aligning ot the intermediate bearing is preferably accomplished during the swaging operation.

Thus, the body portion ('3 of the leal? is formed with an upwardly extending flange 14, audas a result, the juncture between the body portion (5 and the flange 14 is reinforced by the integral bearing arms l3-l11 to such an, extent that strains imparted to the hinge will neither rupture nor distort said juncture.

The hinge section B is formed from a sheet metal blank 1:) which is out to provide a pair of bearing tongues lli lll which project in the same general, direction troin one end o'fthe body portion. The tongues 16am subsequentlyrolled totlt'orln aligned bearings l7--l7 which are ada )lfifl to fit between the outer boa ring armslzl--l2 and the intermediate bearing 11 o the heat A. all of said bearings being eonncrted by the usual pintle 18. The blank 15 is formed with a plurality of screw openings 19, and the marginalportions of the blank are bent downwardly to form a marginal flange 20.

Frornlthe foregoing. it will be observed that I hareprorided the hinge leaf A. with spaced outer l'ieaii'ings which are formed in bearing arms extending from and forming a continuation of the marginal down turned side portions of the body portions that the bearin g arms are integral with and brace the upwardly extending flange, and. as aresnlt the juncture between the body portion and said flange is sufficiently reinforced to pre vent rupture or distortion thereof.

I claim 1. A hinge section. formed from sheet metal bent to "form a. body portion lowing one end thereotbcnt upwardly to form a flange, the marginal side portions of the body portion being bent dowmrardly to Form reinforcing flanges, said reinforcing flanges respectively extending lorwardly beyond theupwardly extending flange and having integral connection therewith to re-intoree the juncture between the body portion and the upwardly extending flange, said too wardly projecting flange portions being respectively formed with hearing openings disposed in a plane aliiote the plane of the body portion, and a. rolled, bearing formed integrally with said upwardly extending flange and disposed intermediate said hearing openings and in alignment therewith.
